L2 cache

(Level 2 cache) A memory bank built into the CPU chip, packaged within the same module or built on the motherboard. The L2 cache feeds the L1 cache, which feeds the processor. L2 memory is slower than L1 memory. See cache.

L2 Cache Locations

Modern CPU chips have a built-in L2 cache; however, L2 caches have resided outside the CPU on earlier computers.

Once data is fetched from the slower main memory, it is then stored in the L2 cache so the processor may then access the information again at a much faster rate, thus improving the performance of the computer.
